PREPARING A GUITAR FOR TUNING

Electric Guitar

To tune an electric guitar, disconnect the guitar's output cable from the
amplifier and connect it to the tuner's INPUT jack.  Turn the volume on
the guitar all the way up.  You can read the tuner's meter, but you do not
hear the guitar's sound.

If you want to hear the guitar's sound while you tune it, you need a
shielded cable (not supplied) with a 1/4-inch phone plug on each end (such
as Radio Shack Cat. No. 42-2381).  Connect one end of the shielded cable
to the tuner's OUTPUT jack and the other end to the amplifier's input
jack.

Acoustic Guitar

To tune an acoustic guitar, place the tuner's MIC as close as possible to
the guitar's sounding hole.  For the best results, play each string
loudly.

TUNING YOUR GUITAR

The tuner receives your guitar's pitch and compares it to a precise
reference pitch generated by the tuner's internal quartz crystal
oscillator.  The tuner then displays the result on the large, easy-to-see
meter so you can tell whether your guitar's pitch is above or below the
reference pitch.

Your tuner uses the following frequencies for each note:

              String                 Frequency

               1E                    329.63 Hz
               2B                    246.94 Hz
               3G                    196.00 Hz
               4D                    146.83 Hz
               5A                    110.00 Hz
               6E                     82.41 Hz

Manual Tuning

1.  Slide the function selector to MANUAL.

2.  Use NOTE SELECT UP or DOWN to set the desired reference pitch.
    The corresponding LED lights to indicate the selected note.

3.  Play the corresponding string and read the meter.  For example,
    if you selected 6E, play the low E string.  If the meter shows -,
    the guitar strings pitch is flat.  If the meter shows +, the 
    guitar string's pitch is sharp.

4.  Adjust your guitar string's tuning peg and play the string again.

5.  After the string is tuned to the reference pitch, repeat Steps 2-4
    for the remaining strings.

After finishing the 1E string, repeat the process with the other strings
to make sure they did not lose their tuning pitch due to the change in
string tension.

Automatic Tuning

1.  Slide the function selector to AUTO.

2.  Follow Steps 3-4 in "Manual Tuning".  The tuner automatically
    selects the note and the LED lights to indicate it.  For example, if 
    the note you play is close to the reference tone for the 5A string 
    (110.00 Hz), the LED on 5A lights.

TUNING HINTS

If a string is seriously out of tune, the meter reading might not be
accurate.  Use another guitar as a reference to approximately tune the
string before using the tuner.

One graduation on the meter scale equals 10 cents.  You can use the
graduations on the meter scale to aid you in tuning.

Note:  A "cent" is a measurement that represents the acoustical interval
between two sounds.  1200 cents equals 1 octave.
